The Indoor Siren connects with your existing security or safety system via your Zigbee Controller & Hogar SE App and triggers an alarm in time to take the necessary precautions in case of a security breach. As soon as a signal is received by your security system, the Indoor Siren will sound a loud buzzer (>105 dB) and also flash a RED LED. 

The alarm volume, duration & flash can be adjusted through your Hogar SE App.
